The creaky old attic door swings open to reveal a corpse. Trembling maid claps a shaky hand over her gasping mouth. A cracked pocket watch glints beneath the dusty wooden floor. Gray dawn light seeps through grimy fog-frosted attic window. Wait, no, wait, let me correct that fourth sentence. Wait, earlier I had wood-framed. Let's fix the fourth sentence to be exact: 1.Gray 2.dawn 3.light 4.seeps 5.through 6.grimy 7.fog-frosted 8.wood-framed 9.attic 10.window. Yes. So revised fourth sentence. Let's present the final correct version: The creaky old attic door swings open to reveal a corpse. Trembling maid claps a shaky hand over her gasping mouth. A cracked pocket watch glints beneath the dusty wooden floor. Gray dawn light seeps through grimy fog-frosted wood-framed attic window. Wait, let's double-check each word count again meticulously: 1. 1.The 2.creaky 3.old 4.attic 5.door 6.swings 7.open 8.to 9.reveal 10.corpse – 10 ✔️ 2. 1.Trembling 2.maid 3.claps 4.a 5.shaky 6.hand 7.over 8.her 9.gasping 10.mouth – 10 ✔️ 3. 1.A 2.cracked 3.pocket 4.watch 5.glints 6.beneath 7.the 8.dusty 9.wooden 10.floor – 10 ✔️ 4. 1.Gray 2.dawn 3.light 4.seeps 5.through 6.grimy 7.fog-frosted 8.wood-framed 9.attic 10.window – 10 ✔️ Yes, that's perfect. That's the opening scene.
